Delik Açma Stratejisinin 3B FDM Baskılı Polimerlerin Mekanik Performansına Etkisi

Öz

Bu çalışmada, FDM yöntemiyle üretilmiş polimerlerin mekanik özellikleri üzerindeki delik açma tekniğinin etkisi incelenmiştir. Dört yaygın malzeme (ASA, PETG, Tough PLA ve Hyper PLA), üç farklı numune tipinde test edilmiştir: deliksiz (NH), üretim sırasında basılmış delikli (PH) ve mikro-delme ile oluşturulmuş delikli (DH). Çekme testleri, SEM incelemeleri, Vicat yumuşama sıcaklığı ve eriyik akış indeksi (MFI) testleri gerçekleştirilmiştir. PH numuneleri, tüm malzemelerde çekme dayanımı ve elastik modülde sistematik bir azalma göstermiştir. DH numuneleri ise tüm malzemelerde artan rijitlik sergilemiş; PETG (%16,2) ve Tough PLA (%7,5) için çekme dayanımında iyileşme sağlarken, ASA ve Hyper PLA’da NH numunelere kıyasla dayanım düşüşü gözlenmiştir. Yüzey pürüzlülüğü ölçümleri, DH numunelerinde PH numunelere kıyasla belirgin derecede daha düşük Ra değerleri olduğunu göstermiş ve delme işlemi sonrasında daha iyi delik-kenarı yüzey kalitesini doğrulamıştır. SEM analizleri, PH numunelerinde halka şeklinde hasar bölgeleri ve DH numunelerinde daha kompakt ve düzgün morfolojik bölgeler ortaya koymuştur. Mekanik özellikler, her bir polimerin termal ve reolojik özellikleri bağlamında açıklanmıştır. Bu çalışmanın bulguları, delik açma tekniklerinin FDM ile üretilmiş parçaların yapısal özellikleri üzerinde önemli bir etkiye sahip olduğunu açıkça göstermektedir.

Effect of Hole-Making Strategy on the Mechanical Performance of 3D FDM-Printed Polymers

Öz

In this research, the effect of hole-making technique on the mechanical properties of FDM-printed polymers is examined. Four common materials (ASA, PETG, Tough PLA, and Hyper PLA) were tested in three types of specimens: no-hole (NH), in-situ hole-printed (PH), and micro-drilled hole (DH). Tensile testing, SEM evaluation, Vicat softening temperature, and melt flow index (MFI) tests were performed. PH specimens demonstrated a systematic decrease in tensile strength and modulus for all materials. DH specimens presented enhanced stiffness for all materials and improved tensile strength for PETG (16.3%) and Tough PLA (7.6%), but strength degradation for ASA and Hyper PLA compared to NH specimens. Surface roughness measurements demonstrated significantly lower Ra values for DH samples compared to PH samples, validating better hole-edge surface quality after drilling. SEM analysis confirmed ring-shaped failure areas around PH and more compact and smooth areas around DH. The mechanical properties were explained in the context of the thermal and rheological properties of each polymer material. The findings of this study clearly show that hole-making techniques have a significant impact on the structural properties of FDM-printed parts.
